You can find classwork and homework for the three weeks I am subbing below:
Monday, January 25th
Intro of CPCTC (Corresponding Parts of Congruent Triangles are Congruent)
checked in diagrams
HW: p259 #1-8, 10-11, 28-31
Friday, January 22nd
Prove It! Class will work through proofs using SSS, SAS, ASA, AAS and HL as the final reason in their proof
How can proving triangles help us? Corresponding Parts of Congruent Triangles Are Congruent (CPCTC)
Homework: Using the Proving Triangles Congruent diagrams, write in what you know once the triangles are congruent
**use different color of pen, this will help us identify and work with CPCTC
Thursday, January 21st
Work day: students were to compare work on proofs from last nights homework
Class/Homework: p243 #1-18, 20-23, 39 and p252-3 #3-5, 7-20
Wednesday, January 20th
It was discovered that AAA doesn't work--all students brought in a 30-60-90 triangle and the observation was made that they were not in fact all congruent.
Students began identifying if two triangles could be proved congruent
Diagrams with congruence statements for methods that work in proving triangles was checked in.
Student were assigned the task of creating diagrams for the methods that DON'T prove congruency
Homework: page 244 #25-28, 31-38, page 255 #34 and
Tuesday, January 19th
Proving Triangles Congruent: SSS, SAS, ASA, AAS and HL
Using wiki sticks students created triangles to test for congruent triangles. SSS and SAS were reviewed, ASA, HL were explored. It was discovered that SSA doesn't work.
Homework: students each need to make a 30-60-90 triangle and cut it out to bring to class tomorrow
Also students were to create notes for each set of givens: SSS, SAS, ASA, AAS, HL, SSA pictures and correct markings should be included along with congruence statements for the givens.
